Concrete-Filled Tubular Column: A Comparative Study of EC4 and AISC 360-10
Concrete-filled tubular (CFT) column is a revolutionary combination of steel and concrete. It takes into account the respective merits and overcomes the limiting characteristics of these materials individually. This is being used worldwide from low rise to high multi-storeyed structures, but still its usage in India is limited due to the unavailability of standard specifications. Thus, a detailed study of EC4 and AISC 360-10 on axially loaded CFT column has been carried out, and their comparison has been made. Also, a database of more than 130 experiments from the literature has been created to assess the suitability of above standards for a large range of parameters. It is found that the predictions of EC4 are in good agreement with the experimental results, whereas the AISC 360-10 shows quite conservative results due to disregard of confinement effect of steel tube on concrete. The application range of EC4 can be extended to concrete of higher strength and to a higher diameter to thickness (D/t) ratio of steel tube. Based on the study carried out on the behaviour of various columns from literature, few refinements in the AISC 360-10 and EC4 are suggested incorporating the above discussed requirements which should be further studied.
